Overview
FOXK2 Recognizes the core sequence 5'-TAAACA-3'. Binds to NFAT-like motifs (purine-rich) in the IL2 promoter. Also binds to HIV-1 long terminal repeat. May be involved in both positive and negative regulation of important viral and cellular promoter elements. 3 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
Protein type: Transcription factor; DNA-binding
Chromosomal Location of Human Ortholog: 17q25
Cellular Component: nucleoplasm; intracellular membrane-bound organelle; nucleus
Molecular Function: protein binding; sequence-specific DNA binding; magnesium ion binding; transcription factor activity
Biological Process: regulation of transcription from RNA polymerase II promoter; regulation of transcription, DNA-dependent; transcription, DNA-dependent; positive regulation of transcription from RNA polymerase II promoter
